Cluster random sample
Step-by-step explanation:
Answer:
x< 3
Step-by-step explanation:
first you do the things between ( )
but here you can't change anything between te ( )
then you do the multiplying and dividing
so in this case you get
-3-24x-36>-111
then you do + and -
so in this case you get
-24x - 39 > -111
then you want to get the x so you bring everything without an x to the other side
here you get
-24 x > -111+ 39
-24x> -72
then you separate the x completely
so you get
x<-72/-24
x< 3
above you changed the > to an < because you divide with a negative number
Since BD is the angle bisector of ∠ ABC,
∠ ABD = ∠ CBD --- (1)
Now, in triangles Δ ABD and Δ CBD,
BD = BD (common side)
∠ ABD = ∠ CBD from (1)
AB = BC (Given)
Hence, Δ ABD ≅ Δ CBD (SAS Rule).
Multiply out the brackets:
4x - 1/4 > 12 - 2x
Add 2x to both sides:
6x - 1/4 > 12
Add 1/4 to both sides:
6x > 12 1/4
Divide both sides by 6:
x > 2.04
Change to a fraction form, therefore the answer is B
Answer: x=-40
Step-by-step explanation: Solve for x by simplifying both sides of the equation then isolate the variable!
Hope this helps you out! ☺
